Are you the only person in America who hasn't seen Avatar? Have no fear, it is still in theaters...217 days and counting since its December 18, 2009 release. You may have quite a drive since it's only in 4 theaters total in the entire U.S., but I'm sure that would be a wise investment of your time, energy, and resources.
I haven't watched many movies in the theater this year, but I saw Despicable Me in 3D with my nephews Owen and Asher and niece Elsie while baby sitting for them last week. I also highly recommend Inception. There are twists and surprises along with stunning visuals.
